When it reaches the limit it surely just crashes. Depending on what your 
limit is, it'll swap a lot before reaching the limit.

I can't test it myself because I don't have a mac.

I would suggest running Valgrind but it's a Linux-only program. What would
be a good equivalent to that on OSX? There's a neat program called "Shark"  
on the Developer Tools CD, but I don't recall whether it can detect memory 

Which version of Miller's pd exactly??
